Case of bilateral seminoma in a trotter stallion.
This report describes a bilateral seminoma in a stallion. After slaughter, histological examination revealed that the tumour consisted predominantly of polyhedral tumour cells with large nuclei, obvious nucleoli and a small border of cytoplasm. The mitotic index was low and Ki67 staining revealed 4% nuclear staining. To our knowledge, this paper is the first using Ki67 staining as a method to evaluate the mitotic rate in a testicular seminoma in the stallion.
